nano technology

As a student of electronics, I had to learn visualising the things, things that can be just drawn or not be seen by eyes. i had imagined electron fighting with each others and electricity and signals flowing. But Today I got a shock with this news of Microsoft HoloLens. It uses the Holograms and just change the world we look digitally. I cant express what it can do so I share the l;ink visit it and see a glimpse of future of our digital generation.

University of Washington scientists have built the thinnest-known LED that can be used as a source of light energy in electronics. The LED is based off of two-dimensional, flexible semiconductors, making it possible to stack or use in much smaller and more diverse applications than current technology allows.
“We are able to make the thinnest-possible LEDs, only three atoms thick yet mechanically strong. Such thin and foldable LEDs are critical for future portable and integrated electronic devices,” said Xiaodong Xu, a UW assistant professor in materials science and engineering and in physics.

Consumer electronics use three-dimensional LEDs, but these are 10 to 20 times thicker than the LEDs being developed by the UW.
